Fire behaviour of modern façade materials - Understanding the Grenfell Tower fire.

J Hazard Mater 2019 Apr 29;368:115-123. Epub 2018 Dec 29.

Centre for Fire and Hazard Sciences, University of Central Lancashire, PR1 2HE, UK. Electronic address:

The 2017 Grenfell Tower fire spread rapidly around the combustible façade system on the outside of the building, killing 72 people. We used a range of micro- and bench-scale methods to understand the fire behaviour of different types of façade product, including those used on the Tower, in order to explain the speed, ferocity and lethality of the fire. Compared to the least flammable panels, polyethylene-aluminium composites showed 55x greater peak heat release rates (pHRR) and 70x greater total heat release (THR), while widely-used high-pressure laminate panels showed 25x greater pHRR and 115x greater THR.
